Abstract: The adverse effect of Respirable Suspended Particulate Matter (RSPM) has become a well-recognised problem in environmental science. Dispersion and dilution of air pollutants are strongly influenced by meteorological parameters, namely wind, turbulence, and atmospheric stability. The analysis of Delhi|s air quality data shows that winter is the most critical season with respect to the concentrations of particulates matter and monsoon is the cleanest. In the present work a stepwise regression technique has been used for predicting the concentration of RSPM in urban Delhi. The models| performance has been further improved by taking a new independent variable i.e., the previous day|s concentration, in addition to the meteorological parameters.

Keywords: regression; RSPM concentration; respirable suspended particulate matter; meteorological parameters; emissions; air pollution; wind; turbulence; atmospheric stability; Delhi; India; urban air quality; modelling.
